🔑 Switch and Case

Let's try making the application to print out the choice that you have input using a switch case.

ℹ️ First, create a variable choice.

---

Then in the parenthesis of switch, key in the name of the input that will be tested, in this case choice.

After the word case, key in the possible choice, as such 'A', 'B', or 'C'.

default means other than the input that you have stated in the case. {% endhint %}

let choice;

switch (choice) {
  case "A":
    console.log("I chose A");
    break;
  case "B":
    console.log("I chose B");
    break;
  case "C":
    console.log("I chose C");
    break;
  default:
    console.log("Please make a choice");
}

In fact, this can actually be done using if and else statement! This is how to do it:

if (choice === 'A'){
    console.log('I chose A');
}
else if (choice === 'B'){
    console.log('I chose B');
}
else (choice === 'C'){
    console.log('I chose C');
}
else{
    console.log('Please make a choice');

Now, let's try an exercise!

Exercise

I have strawberries, mango, durian. I want the application to print out "I Love Strawberries!" if I choose A , and mango if i choose B, vice versa.

Want Answer? Press me!

let choice;

switch (choice){
    case 'A'
        console.log("I LOVE Strawberries!");
        break;
    case 'B'
        console.log("I LOVE Mango!");
        break;
    case 'C'
        console.log("I LOVE Durian!");
        break;
    default:
        console.log("Please make a choice.");
}
